I replaced a Performance MX with an MX Master around a month ago and whilst the mouse itself is lovely and all, there are a few irritants with the software. - Logitech Options disables pointer acceleration on startup, so have to go into windows mouse options to re-enable every restart. No settings in Options that I can see to enable pointer acceleration. - Over bluetooth the mouse reconnects every 2 seconds, making it entirely unusable. I'm using it with the unifying receiver now, but would prefer BT. - Sometimes the mouse seems to switch into "dumb mouse" mode, with only the two main buttons and scroll wheel working - middle, back/fwd, side wheel etc disabled. Switching the mouse off and on sorts it. Anyone else run into these, and know of a fix? Logitech's forums are entirely unhelpful, with "please contact support" being the standard response, followed by a long and drawn out waste of time it seems.
Hey Tad, not had those issue per-se, but make sure the receiver is plugged into a USB2 port, not USB3 preferably as far away from a USB3 port as possible, as there are "known issues" with interference.
Hmm, weird. I don't really have much of a choice unfortunately. I can plug it into the hub in my monitor or my TB dock - both have USB2s and 3s right next door to each other. It's in the monitor at the moment. Well, it's in a USB2 in the monitor, which is USB3 to to the dock, which is TB3 to the PC, to be more correct. Do you use pointer acceleration on yours? If so does the (windows) setting stay enabled through a restart?
Sorry mate, not a foggiest, don't use pointer acceleration (I think). I only got it for the size/comfort and the better battery life than the Performance. Which for such a capable mouse is a bit daft...
Odd that there's USB2>3 crosstalk issues. Surely that's down to individual USB hubs and/or motherboard controllers being of a poorer quality than others? I certainly don't have crosstalk issues with my motherboard or external USB hubs. I don't have that particular mouse admittedly but if you're getting crosstalk with the mouse, it stands to reason you'd get it with other devices too.
I use mine with BT and never had a problem with it disconnecting. Any chance you've been unlucky and picked up a duff one?
Hmm, perhaps I have. It seems a fairly pervasive issue, so I assumed it was software/config related. I have a few days left to do an Amazon swap, so no harm doing that.
I'd get it swapped, I use mine over BT with 3 different machines and never had it drop out on any of them, sounds like you may have got a duff one. I love it so much I've just ordered another to leave permanently at the office.
Replacement on its way from Amazon, mayhaps if I get the BT working the other irritants will go away, if they're related to being double-hubbed. Just thinking I use my MX anywhere 2 with no such issues, and it seems likely they're the same innards to some extent, so perhaps mine is indeed duff.
Sounds like it could be faulty hardware - I've not had issues with mine either. The software isn't the best admittedly and for a while I had a conflict with it and MSI Afterburner (at least I think that was the conflict) but an update seemed to sort that out.
I take it this is with Bluetooth? If so, do you have any potential 2.4GHz interference sources? Video senders, wireless speakers, smart home devices etc? Try disabling the 2.4GHz band on your router (if you can) and any 2.4GHz devices then test again. I had this issue years ago and it turned out to be the magic eye TV sender for my old Sky box, which got immediately binned but anything in the 2.4gig range can mess with BT connections.
Bluetooth is an issue, yes. The unifying receiver behaves just fine, apart from the quirks mentioned. In terms of other 2.4GHz devices, there's shedloads to be honest... wifi devices on channels 1 & 11, a bunch of Sonos on channel 6, bunch of Hue on Zigbee 15 (2.425). Not many devices in the office where I'm having the issue though, a wireless keyboard that I can't switch off, an echo that I've just tried to switch off and no change, and the laptop I'm using. I have an MX Anywhere 2 as well though, and that works on BT without a hitch, even at significant range, so it would surprise me if interference is the issue. Even if it is, there's not really much I can do to prevent it.
If you've got other BT devices working as they should, then it has to be the MX Master's assigned BT frequency/channel is conflicting with something else in your RF environment. 2.4GHz is very penetrative and it may well be that a neighbours emissions are causing your problems. If you can test the mouse in somebody else's house or in an office to rule out your home's unique RF spectrum, then at least you'll know it's not the mouse itself.
I've just paired it to a tablet, so the mouse itself is fine. And the laptop is fine, given that I can use other BT devices with no problems. But the two just don't get along with each other
Hmm, seems a stretch. BT is delivered courtesy of an Intel 8265, and no issues with any other BT devices. I would have thought a fundamental incompatibility between such a ubiquitous wireless adaptor and the mouse would have been flagged in many places on the tubes, which leaves something to do with my specific SW/HW configuration. Lots of people using the laptop with the MX Master, though presumably with the standard-fit Killer 1535 card. I do still have the old card somewhere I can swap out for, but whilst that may prove a point, I'm not about to go back to using that in anger on account of the wifi reliability. I've dicked about with device-level power settings for anything remotely associated with bluetooth, disabled Bluetooth AMP, and a few other tweaks that I picked up from various locations. I suppose temporarily swapping the adaptor, whilst a pain, might at least narrow the problem down.
